DUIVIPING-WAGON.

To all whom it may concern Be it known that I, JOHN I'IEBERLING, in the county of Monroe and State of New York, have invented anew and useful Improvement in Dumping WVagons, which improvement is fully set forth in the following specification and shown in the acdrawings. J

The present invention relates to dumping wagons of the type in which flexible connections are employed for controlling the doors or movable dumping sections of the wagon body, an object of this ing to provide a construction having-a slack take-up device for one of the connectors so constructed'and arranged that the jar or strain, due to the sudden. opening of the doors, is not imposed upon said take-up de: vice, the latter being engaged by the flexible connections only as the doors approach closed position.

Another object of the invention is to construct this take-up device so that it will equalize the strain on the connections.

To these and other ends the invention consists in certain parts and combinations of parts all of which will be hereinafter described, the novel features being pointed out in the appended claims.

In the drawings, Figure 1 is a vertical longitudinal section through a dumping wagon-constructed in accordance w1th this invention; Fig. 2 is a vertical transverse section showing the front of the winding means just prior to the closing of the movable doors or sections; Fig. 3 is a detail view of the winding means, showing the position of the equalizer when the doors are closed; Fig. a is an enlarged axial section of the winding shaft, showing the position of the equalizer when the doors are fully open; Figs. 5, 6 and 7 are three views of a modification of the invention, Fig. 7 being a section on the line b?) Fig. 5; Figs. 8 and 9 are detail views of a modification in which the take-up device is not in the form of an equalizer, Fig. 8 being a front view of the front end of the wagon body and the winding means, and Fig. 9 being a broken longitudinal vertical section of the wagon body; and Fig. 10 is a transverse section through a winding shaft of another embodiment of the invention.

In carrying out this invention, a wagon body of any suitable construction may be employed. In the present instance, the body consists of a front end board 1 and a back Specification of Letters Patent.

end board 2 connected by side boards 3 which are extended in front of the front board and in rear of the rear board. The body may have two doors or sections 4: preferably hinged at 5 to the side boards 3 and one of sald doors having a batten strip 3 7 6 at its free edge for overlapping thefree edge of the other door.

For controlling the doors, two flexible connectors 7 and 8 may be provided, said connectors, in this instance, being separate from each other .and each being attached at 9 to a hook on the rear board 2, thence extending forwardly along the free edges'of one of the doors 4: over guides 10 to a guide 11 arranged on the front ends of the connectors being attached at 12 to a winding drum or shaft 13 which is j ournaled on the side pieces 3 at the front of the vehicle. For winding the flexithe front board of the body,

ble connector on the winding means or .the

winding shaft, there may be provided a hand lever 14: turning on the shaft 13 and carrying the pawl 15 which cooperates with a ratchet wheel 16 rigid with the shaft 13.

Also cooperating with the ratchet wheel 16 is a locking pawl 17 pivoted at 18 to a swinging member 19 which, in turn, is pivoted at 20 to the forwardextension of one of the side frames 3 and has a bifurcated portion 21.

Operating between the arms of the bifurcated portion is a pin 22 carried by a swinging foot-operated member 23. When the pin is located out of engagement with the arms of the bifurcated portion 21, the pawl 17 will ride over the ratchet 16 and hold the latter in any position to which said ratchet may be adjusted by the lever 14. When the pin is located in engagement with the upper arm of the bifurcation the pawl 17 is thrown out of engagement with the ratchet wheel 16 permitting the drum to unengages the lower arm of the bifurcation, the member 19 is held against movement so that, during the travel of the vehicle, the pawl 17 cannot be accidentally disengaged from the ratchet 16.

The foregoing parts are not claimed per se in this application, a feature of this invention being the provision of a slack takeup device for one of the flexible connectors and preferably the one which controls the door or'section carrying the batten strip 6, so the other door may close first and then be overlapped by the batten strip, the

will not be imposed on one connection, thus subjecting the latter to breaking.

In the embodiment shown in Figs. 1 to 4, the equalizer is in the form of a member 24 pivoted to the winding shaft 13 to turn about an axis25 extending transversely of the axis of said shaft 13, the member being secured to the shaft between the connector attaching points 12 so, that both connectors may engage with the equalizer. The equalizer has a tendency to'sw'ing outwardly to the position shown in Fig. 1 and this tendency is effected by making the outwardly swinging end 26 heavier, so that, when. the

winding shaft rotates rapidly on the unwinding of the flexible connectors, I the heavier end will swing outwardly under the action of centrifugal force.

7 To the end that the connectors will be directed toward the equalizer or take-up upon the winding of said connectors, the shaft may be formed with right-and left hancl spiral grooves-27, each leading from one of the attaching points 12 toward the equalizer.

As the shaft 13 is turned, the connectors '7 and 8 follow in the grooves 2-7, the connector 7 first engagin'g'the equalizer by entering the groove 28 thereof, thus holding the adjacent end of the equalizer against the shaft 13. The other connector 8'then engages within the groove 29 of the equalizer and, as the adjacent end is separated from the shaft 13, more of the connector 8 will be taken up and the door i controlled thereby will move in advance of the door carrying the batten strip 6. After the door controlled by connector 8 reaches the closed position, a further turning of the shaft 13 will'cause the equalizer to turn on its pivot and assume the position shown in Fig. 3, thus taking up the slack in the connector 7 and causing the door with batten strip 6 to close with equal strain on both connectors '7 and 8.

In the embodiment of the invention shown in Figs. 5 to 7, the shaft 13is provided with the grooves 27 leading from the connector attaching points 12 to an equalizer. The latter, in this instance, comprises a pivoted or rocking member 30 secured to the shaft 13 by straps 31 to turn about an axis extending longitudinally of the shaft 13. The opposite ends of the rocking member 30 carry arms 32 preferably extending in opposite directions from the axis of the shaft,

' the form of a so that one of said arms will be engaged by one of the flexible connectors before the other arm is engaged by the other flexible connector. In this way, the arm, that is engaged second, takes up more of its connector than the arm engaged first, thus moving one of the doors in advance of the other until such door is closed, when the strain on the connectors causes the member 30 to shift and equalize such strain on both connections, at the same time, effecting the closmg of one door lIlyiLdVBJlCG of the other.-

In the. embodiment of the invention shown in Figs. 8 and 9, the shaft 13 is provided with grooves 27 in which the connectors'7 and 8 are wound. Thelconnector 8 18 shorter than the connector7?,while thelatter I q is provided with'a turnbuckle 33 or other device for varying the length of said con-. nector 7*. The slack take-up device is in the form of a the winding shaft or connector 7 as the door controlled by the connector 8* movement, the projection 34 causing the connector '7 to be taken up faster, at this time, than the connector 8 and thus closing the door carrying the batten strip'6 about the time that the other door closes. buckle 33 permits the adjustment of the connector 7 so that the tension on the connectors 7 a and 8 will be equal.

In the embodiment shown in Fig. 10, the operation of the parts is similar to that of Fig. 9, an adjustable projection 34 in the form ofacurved strip of sheet material is secured at one end at 35 and has the other end engaged by an adjustable support 36 in screw extending through the shaft 13 and held against movement by a lock nut 37. With this construction it is unnecessary ment of the projection will take-up for any slight difference inlengths between the two connectors.

From the foregoing, it will be seen that there has been provided in all embodiments oro ection or enlar ement 3% on' b drum 13 engaging the to provide adjustment in one of the flexible connections, as the adjust-V nears the end of the closing The turn a slack take-up device which is not engaged i by the flexible connectors until the doors near closed position, and, in this way, the wear on the take-up is reduced to a minimum. At the same time, the take-up is mounted on the winding means and is in full view of the operator of the wagon so that he may be assured that such take-up is operating properly.

Another important advantage for the arrangemen't of the take-up is that the latter is not affected by the position ofthe wagon body and therefore the doors maybe closed upon a hillside while the Wagon is inan inclined position, the doors operating so that the one'without the batten strip will be the first to close.

' least two doors,

. nector.
